Set segmentation fault handler

Question

In my signal.h file I have added a signal handler like this: #define SIG_WPG ((__sighandler_t)3) and then implemented it in signal.c like this: if (ka->sa.sa_handler == SIG_WPG) { unsigned long ul_cr2 = current->tss.cr2; unsigned long ul_eip = (unsigned long) regs->eip int ul_cr2_rounded = ul_cr2 & PAGE_MASK; printk("ul_eip: %d\n", ul_eip); printk("ul_cr2: %d\n", ul_cr2); printk("ul_cr2_rounded: %d\n", ul_cr2_rounded); } How can I make this signal handler handle segmentation faults in user space?

Answer 1

You can use the signal() method to register a callback for that exception: //callback prototype void Handler(int sig); //register the callback for the specific signal signal(SIGSEGV,&Handler);
